摘　　要：针对方铅矿单矿物,分别使用瓷罐瓷球与瓷罐铁球磨矿并进行浮选,考察磨矿时间、矿浆溶液的酸碱度、捕收剂的用量与方铅矿浮选效果的关系。结果表明,瓷介质磨矿比铁介质磨矿更有利于方铅矿的浮选;高碱环境有利于方铅矿的浮选;捕收剂用量越高越有利于方铅矿的浮选;采用铁介质磨矿时,磨矿时间延长,方铅矿浮选回收率降低,而采用瓷介质磨矿,磨矿时间对其影响不大;采用铁介质磨矿,铁介质氧化生成羟基氧化铁覆盖在方铅矿表面,改变了方铅矿表面组成,增加了方铅矿亲水性,对方铅矿的浮选产生负面影响。For galena mineral, after grinding in porcelain jar using porcelain ball and iron ball, the effects of grinding time, slurry pH and collector dosage on galena flotation recovery were investigated. The results show that the ceramic grinding medium is more conducive to galena flotation than iron grinding medium;high alkali environment is conducive to galena flotation;collector dosage is higher for flotation of galena;using iron medium grinding, grinding time, galena flotation recovery rate decreased, and grinding with ceramic media. With the ceramic grinding medium, grinding time has little influence on galena flotation recovery;the iron, iron oxidation of ferric hydroxide medium covered on galena surface, change the galena surface, galena increased hydrophilicity, have a negative impact on the flotation of galena.
